There is a really interesting generation gap issue in the replies to your comment. What I perceive as younger people are horrified at the idea of fifty year old tools while the older folks are thinking (I imagine) “if the tools have lasted that long they must be well-honed and very good”.
Of course, this could simply be the perspective of someone turning 50 this year.
